本文将SO（t）群的对称性理论应用到双电子体系中,算出了同壳电子激发态的能级数值。再利用拟合参量修正,并对非同壳电子的不同有效核电荷数变分,给出较适用的双电子体系中双里德伯激发态的计算公式,计算了（?）≤5,z≤15的双里德伯激发能级的数值。研究了随原子序数z的增加,双里德伯激发态能级的变化规律。

Doubly excited states of two-electron atoms and ions are formed through electron-electron correlations.In some collisions doubly excited states are formea most frequently by double-electron-rapture processes or by simultanous electron capture and excitation of the projetiles.Using the so(4) group theory in a basic assumption of the present model in which the two electrons are limited to the same average distance from the nucleus is successful. This paper deals with the variational parameters to calculate the double Rydberg exci...
